Are European flights considered international?

If they're from one country to another in Europe, they are by definition international flights, yes.



In 2026, the definition of "international" for European flights depends on whether you are crossing the Schengen Area borders or the European Union (EU) customs borders. For a flight between two Schengen countries (e.g., Paris to Rome), the experience is functionally "domestic"—there are typically no passport control lines, though you still need valid ID. However, flights between an EU country and a non-EU country (like London to Paris or Dublin to Madrid) are strictly International, requiring full passport checks and customs declarations. A major shift in 2026 is the implementation of the ETIAS (European Travel Information and Authorisation System), which requires travelers from over 60 visa-exempt countries (including the U.S.) to obtain a digital authorization before flying into the Schengen Zone. Thus, while the "flight" might feel short, the legal and regulatory framework in 2026 treats almost all cross-border European travel as an international transit.
